Reminds me of a certain NTL Macintosh Tech Suppport Person (who shall remain nameless) way back in the days of NTL Tech Support in Cleppa Park in Newport.
They had a Tech on the night shift who while walking a customer through some Macintosh problems with configurations etc asked the customer to restart the Macintosh and placed them hold.
Several hours later he awoke from his nap only to find to his bemusement the customer still onhold and said ok then has the Mac restarted and sorry for the delay as he was making some checks from his side and calmly proceeded with the call.
